But even yummier than that?? A jubilant Leo getting on the mic to spit some mad rhymes!

Lino Meoli, the DJ at the event, revealed:

"Leo was on the mic beat-boxing to 2 Chainz and had all his buddies up [on] stage."

Meoli also adds that even though Leo recently broke up with his Victoria Secret model girlfriend of 10 months Erin Heatherton, the film star was NOT romancing the many women hitting on him at the event.

The DJ shared:

"The girls were definitely all over him. He was more with his boys, hanging with the rappers, getting on the mic. I didn’t see him with the girls at all."

Aww cute! You do YOU, Mr. DiCaps!

AND apparently, the party people raged out at The Darby until about 5am until moving to Avenue where the shindig lasted for another couple of hours.

But perhaps the sugary icing on the cake is that Leo's party raised boatloads of money for charities supported by the Leonardo Dicaprio Foundation, including A 500k donation made directly to the American Red Cross for Hurricane Sandy relief!

Shane Redway -- a Canadian rapper and close friend of Drake's -- was killed early Saturday morning in a car crash. He was just 26 years old.

Redway and two others were killed when their car lost control, struck a guardrail and burst into flames. The crash occurred around 4am outside Pearson International Airport in Toronto. It's unclear who was behind the wheel. Police are investigating the crash.

Drake took to Instagram to remember Redway, posting two different tributes.
